A TISSUE FACTOR INFLUENCING SUCCINIC DEHYDROGENASE ACTIVITY IN TUBERCULOUS GUINEA PIGS

Abstract
The alterations in succinic-dehydrogenase activity during the course of infection with Mycobacterium tuberculosis strains H37Rv and BCG, as well as with dead bacilli, were described. A tissue factor was described which is prepared from normal bovine kidney and will restore enzyme activity in vitro. This factor is prepared by chromatographic analysis and contains a nucleotide with an UV absorption maxima at 250 mu (pH 3) and a free sulfhydryl group. The role of this factor in the response to tuberculosis is discussed.
